I have an old record that has some clipping effect that happened during recording. This is a song, so i can't just cut out all frequencies probably ... is there any smarter way around to get rid of that clipping?

You can't actually remove clipping - in recording your levels were too high so your waveforms were damaged at that point. Nothing can bring back the originals, andv even filtering can only be used to remove some of the frequencies that may have been caused.
